OWNER’S MANUAL Digital Multimeter DMR-3600 CIRCUIT-TEST ELECTRONICS LTD A Division of R.P. Electronic Components Ltd. Burnaby, BC, Canada V5C 5Y1 www.circuittest.
INTRODUCTION Your Circuit-Test DMR-3600 Digital Multimeter incorporates the latest technology providing you with a feature packed instrument. With it you can measure a wide range of voltages, current, inductance, capacitance and resistance in the lab, shop, car and home. This meter has been designed for the Electrician, Technologist, Hobbyist and Educational Institutions.
High voltage AC and DC circuits are dangerous. Use caution when working above 60VDC or 30VAC rms as these voltages pose a shock hazard. Always consider circuits to be energized. Never assume any equipment is deenergized. Lack of caution or poor safety practices can be very dangerous and/or lethal. SPECIAL FUNCTION MAX - When MAX is pressed, the last reading is held on the display until a higher reading is recorded. When using the MAX position on the Frequency range, the autoranging feature is disabled.
Capacitance: 4n-40n-400n-4µ-400µF ± (5% + 10), ±(8% + 10) (above 100µF) (Test voltage: 3V / Test frequency: 4n-40nF 1KHz; 400n-4µF 70Hz; 400µF 7Hz) Frequency: 4K-40K-400K-4000KHz ± (0.5% + 1) (Autoranging) (Sensitivity: 0.2Vrms minimum) Inductance: 4m-40m-400m-40H ± (5% + 10) 4H ± (5% + 20) (Test frequency: 4m-40mH 1KHz; 400mH-4H 70Hz; 40H 7Hz) Transistor HFE: 0-999 HFE Test base current: 10µA / Test voltage: 3.0 ± 0.4V Diode : Test current: 1.0 ± 0.6mA / Test voltage: <3.5V Logic: Logic High 2.8V ± 0.
1-4 1-5 1-6 Apply the test leads to the circuit to be measured. Ensure that the black lead is connected to the negative side of the circuit and the red lead to the positive. Read the displayed voltage. If the minus (-) sign appears the voltage is negative at the point being measured. 2 AC VOLTAGE MEASUREMENT ! 2-1 2-2 2-3 2-4 2-5 WARNING: Maximum input is 750V AC (RMS). Plug the red test lead into the VΩ jack and the black test lead into the COM jack.
4 AC CURRENT MEASUREMENT WARNING: Remove all power from circuit being tested when checking current. When using the 10A range do not connect to the circuit for more than 60 seconds and wait 10 minutes between 10A measurements. 4-1 Plug the red test lead into the mA jack and the black test lead into the COM jack. If the current being measured is between 400mA and 10A insert the red test lead into the 10A jack. 4-2 Set the DC/AC switch so that AC is displayed on the LCD.
3. When using the 4000 MΩ range a fixed 20 count must be subtracted in order to obtain a true measurement. For example when measuring a resistance of 1200MΩ, the display will read 1220MΩ. 6 CONTINUITY TEST ! 6-1 6-2 6-3 6-4 WARNING: Remove all power from circuit being tested when checking continuity. Discharge any charged capacitors. Never connect the probes to any voltage while the range switch is set to 400 . Plug the red test lead into the VΩ jack and the black test lead into the COM jack. setting.
9 FREQUENCY MEASUREMENT WARNING: Maximum input is 500 V. 9-1 Plug the red test lead into the VΩ jack and the black test lead into the COM jack. 9-2 Set the range switch to the KHz setting. 9-3 Connect the probes to the point of measurement. 9-4 Read the displayed frequency. NOTE: When using the Frequency measurement position the autoranging feature can be disabled by pressing the MAX switch.
13 BATTERY REPLACEMENT ! 13-1 13-2 13-3 13-4 13-5 WARNING: Disconnect both test leads from any equipment before removing back cover. Do not use meter with case opened. The “ ” will appear on the display when the battery requires replacing. Disconnect both test leads and turn off the power. Remove the screws in the rear cover of the case and remove the cover. Unsnap the battery from the connector and replace with a new 9V battery. Replace the cover and cover screws.
